For incoming, right? For outgoing, you shouldn't need a special router rule. You're right. The router will not block outbound connections over www, pop and smtp.(at least I don't have it configured to do so!). But it will block inbound connections - so you need to set up port forwarding to allow selected ports in and to NAT them to an inside server. But - reading the original note, he was asking about outbound ports, so my post has been completely (um, er, ahem) off topic.

Re: Outgoing SMTP ports
My problem seems to persist, let me delve more into it and see if y'all can help. My firewall allows all incoming and outgoing connections that are ESTABLISHED or RELATED My firewall allows all incoming connections on port 25 that are NEW (TCP) My firewall allows all outgoing connections to port 25 that are NEW (TCP) Is there some other rule that I need to set because outgoing mail is just not going, I have my 3 nameservers setup in /etc/resolve.conf and can dig all the domains which mail should be going to so DNS doesn't seem to be the problem. Any suggestions? -James -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Re: Outgoing SMTP ports
I figured out the problem. My firewall was applying the same rules to my eth0 and lo interfaces, so I set the first rule in my inbound and outbound sets to allow any traffice on lo... Is there any security risk posed by this? Should I be security concious about have no restricitions on the loopback interface? -James On Oct 29, 2003, at 7:35 AM, James W.
